This invention relates to a heater for use in automobile bodies, one of the objects being to provide a hot water heater which is not dependent at all times upon the temperature T of the water in the cooling system but can exhaust manifold after the water in the heating system has reached a desired temperature, so that thereafter the temperature can be maintained by the water circulating through the water'jacketof the engine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereindisclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. In the accompanying drawings, the preferredform of the invention haspeen shown. In said drawings: Figure l'is a side elevation of an automobile engine equipped with the present improvements.

Figure 2 is an enlarged view partly in side elevation and partly in section of the super heater attached to an exhaust manifold, a

portion of which has been shown.

Figure 3 is a section on line 33, Figure 2.,

Referring to the figures by characters of reference, E designates the engine of an automobile, the radiator R of which is connected thereto by upper and lower pipes U and L respectively, as commonly employed. The exhaust manifold has been indicated at M. The hot Water radiator has been indicated at 1 and extending thereto from the pipe L is a pipe 2 forming a part of the heating system. Another pipe 3 is connected to the radiator while a third pipe 4 is connected to pipe U.

The superheater constituting the principal part of the present invention consists of a casing 5 a portion of which can be formed with a water jacket as at 6. This. water I j acket extends partly around a heatingchamber 7 andopening into this heating chamber is a neck 8 which is adapted to be attached to the manifold M by screwing it into an aperture 9 formed therein. The pipe 3 is connected to oneend of the water jacket 6 while pipe 4 is connected to the other end thereof.

A butterflyvalve 10 can be arranged within theneck 8 and this can be actuated by means of a rod 11 extending to someoperating means within convenient reach of the driver. The rod is connected to a crank arm 12in the structure so that by moving the rod in one direction the butterfly valve will be closed and by moving it in another direction the valve will be opened.

' Obviously thewater jacket 6 and pipes 2, 3 and 4 will be filled with Water forming a part of the engine-cooling system and this Water will be free to circulate through the pipes and water jacket as the Water circulates betweenthe engine and the radiator. After the engine has been started and before the water in its jacket has become Well heated, butterfly valve 10 can be opened. Thus hot gases discharged into the manifold M can be deflected by the butterfly valve into the heating chamber 7 so as to quickly raise the temperature of the waterin the jacket 6. The Water thus quickly heated will be supplied to the heater l'from which it will return to the pipe L by Way of pipe 2.

After the engine has been running long enough to raise the temperature of the water in its cooling system sufficiently to permit its use for heating purposes the butterfly valve 10 can be closed thereby cutting off the discharge .of hot gases into the chamber 7 Although the superheater has been shown provided with a water jacket it is to be understood that water can be conducted therethrough by any suitable means.

What is claimed is:

A superheater for the Water of the cooling system of a Vehicle engine, including a casing having a heating chamber, a neck opening into the chamber for attachment to and communication with the exhaust manifold of the engine, a butterfly valve in and normally proj ecting beyond the neck, means for actuating the valve to control the flow of hot gases through the neck into the heating chamber, said valve when in normal or full open position constituting means for deflecting hot gases into the neck, and a Water jacket extending partly around and integral with the casing and having openings at opposite ends thereof fo'rrespectively receiving Water from and deliveringit to said cooling system.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature.

WILLIAM J. WADE.
